By train:

Travel to Berlin Hauptbahnhof or Berlin Ostbahnhof. 
From there take the suburban train "S7" in direction "Ahrensfelde" to "Marzahn". 
Attention: DB/S-Bahn seems to be doing construction work between S Lichtenberg and S Ostbahnhof. There will be rail replacement buses, but it's easier to go by Tram M6 from Alexanderplatz. 
From the Station "Marzahn" you can either walk to the partyplace (about 2 km) or take the Tram M6 in direction "Hackescher Markt" for one Station till "Gewerbepark Georg Knorr". From there you can reach the place afoot.

By plane:

From airport Schönefeld (SXF) take the suburban train "S9" in direction Pankow until Station "Landsberger Allee".  (Attention: in the moment there are construction works at the train-station "Landsberger Allee". Because if that there  is a replacement tram station a few meters further from the suburban train station. Just follow the mass of people leaving there and you will find it.) From there take the Tram M6 direction Marzahn until "Gewerbepark Georg Knorr". 

From airport Tegel (TXL) take the TXL-Shuttle-Bus to Alexanderplatz.
Attention: DB/S-Bahn seems to be doing construction work between S Lichtenberg and S Ostbahnhof. There will be rail replacement buses, but it's easier to go by Tram M6 from Alexanderplatz. 
Btw. There might be the possibilty of the train drivers on strike so please read the Deutsche Bahn-website for updates of these matters.

There is a supermarket just 100 m from the partyplace. Keep in mind that the marketplace is closed friday (friday is a official holiday in Germany) and sunday. In addition there is a 24h gas station within walking distance.

We also offer reasonably priced food on site. Delicious vegetarian food and a selection of meat and sausages for your barbequeing needs (grill is also on site). You also have the opportunity to get some breakfast for a small fee.
